Gravity normally open flap drain

Abstract

The invention provides a gravity normally-open type turnover plate drainer which comprises a pipe body. A turnover plate is arranged on the upper portion of the pipe body. The gravity normally-open type turnover plate drainer is characterized in that two opposite turnover plate mounting portions are arranged on the outer circumference of the turnover plate and symmetrically arranged on one side of the turnover plate; the connecting line of the axes of the two turnover plate mounting portions is located beside the center line of the turnover plate, and the positions, at the two sides of the connecting line, of the turnover plate comprise a large turnover plate portion and a small turnover plate portion; the turnover plate mounting portions and a pipe body mounting portion arranged on the pipe body are rotatably connected in an inserted mode, and the turnover plate can swing around the axes of the turnover plate mounting portions; a turnover plate locating portion is arranged on the outer circumference of the large turnover plate portion and corresponds to a pipe body locating portion arranged on the pipe body, and when the turnover plate is horizontal, the turnover plate locating portion and the pipe body locating portion are connected in an inserted mode. The turnover plate can be automatically kept vertical or in a large-angle opened state; smooth drainage is guaranteed; the drainer is convenient to use, sanitary and long in service life.

Description

technical field [0001] The invention relates to a sanitary fitting, in particular to a gravity normally open type drainer with a flap. Background technique [0002] Basins and bathroom cabinets are essential supplies for toilet installation. The basin bodies of the table basins and bathroom cabinets are provided with drain holes, and openable and closable drains are installed in the drain holes, and the drains are connected to the sewer pipes. According to the mode of opening and closing of the sealing plate, it can be divided into a flap drain and a bouncing drain. The bouncing drain is reliable in opening and closing, and has a stylish appearance, but has a complex structure and a short service life; while the flap drain has a simple structure and a long service life. When the flap is horizontal, it seals the upper port of the drain, and when the flap is tilted to the vertical state, the drain is opened from small to large, but the vertical state of the flap cannot be main...

AI Technical Summary

Problems solved by technology

According to the mode of opening and closing of the sealing plate, it can be divided into a flap drain and a bouncing drain. The bouncing drain is reliable in opening and closing, and has a stylish appearance, but has a complex structure and a short service life; while the flap drain has a simple structure and a long service life. When the flap is horizontal, it seals the upper port of the drain, and when the flap is tilted to the vertical state, the drain is opened from small to large, but the vertical state of the flap cannot be maintained, and it is often closed or in a state of collision due to water flow or washbasins. The small inclination angle leads to slow or impossible drainage. You have to use your hands to pull the flap to keep it upright. It is inconvenient to use, and your hands will touch dirty water, which is not hygienic and affects your mood.
